Thermal mass flowmeters are widely used in various industries due to their ability to measure the flow rate of gases accurately. Here are some applications of thermal mass flowmeters across different industries:

Thermal gas mass flowmeter adopts the principle of thermal diffusion, and thermal diffusion technology is a technology with excellent performance and high reliability under harsh conditions.

The origin of the thermal gas mass flowmeter is from the hot wire anemometer. The temperature of the platinum heating wire has a proportional relationship with the change in the flow rate of the fluid: the faster the flow rate, the more heat is taken away.

Thermal gas mass flow meter is used to measure and control the gas mass flow meter, different from other gas flow meters, do not need to carry out pressure and temperature correction, directly measure the gas mass flow.

When selecting a thermal mass flowmeter, several important factors should be taken into consideration to ensure it meets the requirements of the application and provides accurate and reliable measurements. Here are key points to pay attention to:

At present, oxygen generator in the production process will be affected by external influences, more and more enterprises for fine management, energy consumption, cost accounting and other requirements for the loss of this part of the oxygen measurement.

The thermal mass flowmeter sensor part is composed of two reference platinum resistance temperature sensors, using a bridge loop, one sensor measures the fluid temperature, and the other sensor is a heating element, maintaining a constant temperature difference higher than the fluid temperature, that is, when the gas flows through the heating element, the heat is taken away, and the heat is proportional to the flow rate of the gas and the density of the gas. To maintain a fixed temperature difference between the two temperature sensors requires the circuit to provide more power to the heating element, and the amount of output power in the circuit is related to the mass of the fluid, thus measuring the flow rate.
